Subject: Randomize control points in metapost/metafun?

Hi!

I look for a way to randomize control points of a path, leaving the
coordinates themselves untouched.

The reason is the following: I want to draw (for example) a circle
with a triangle inside, and I want them to look slightly randomized.
If I do (see attached pdf for a typical result of this)

\startMPpage
draw fullcircle scaled 2cm randomized 0.1cm;
draw ((1cm,0)--(0,1cm)--(-1cm,0)--cycle) randomized 0.1cm;
\stopMPpage

then the corners of the triangle does not stay on the circle (and I
want them to). [I dont want the triangle to consist of perfectly
straight lines, so I cannot (directly) draw the triangle using
different points along the randomized circle] I imagine that one could
achieve what I want if one could randomize the control points only.

Also, is it possible to randomize a picture (consisting of several
paths/points) somehow, without randomizing each part of it manually?

/Mikael
